Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Bishop's Stortford (CM23) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Leaks at bars or ridge
- Cappings lifted or rattling
- Corrosion at cut edges or fixings in coastal areas
Why it happens
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.

Guide prices for aluminium roof lantern repairs in Bishop's Stortford
Typical range: £195–£695 ex VAT, which is £234–£834 with VAT, per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
